Cooling water strainer model 525
Use and maintenance
• Inspect the strainer element regularly for
contaminents.
N.B. The lid doesn’t need to be removed for
inspection.
• Clean the strainer element if dirt has accu-
mulated.
• Close the seacock. Unscrew the knurled
knobs and remove the lid of the water
strainer, see drawing 5.
• Remove the strainer element out of the
housing and ush the strainer with clean
water.
• Re-install the strainer element and reinstall
the lid.
Secure or loosen the knurled knobs al-
ways manually. Never use tools for this
purpose, see drawing 6 and 7.
Check the seal between lid and housing after
cleaning and re-assembling the strainer. An
improperly sealed lid will result in air sucked
in by the sea water pump of the engine which
again will result in overheating of the engine.
To prevent damage of the water strainer, dur-
ing frost in the winter time, either the water
must be drained or the installation must be
lled with anti-freeze.
Remove the hoses to drain the strainer; the
housing is not equipped with a drain plug.
Take care that during lling with anti-freeze
no anti-freeze is spilled into the waterway.
Anti-freeze is poisonous.
